Board 1 - Tape Sensors

Tape sensor output is fed into a transresistive circuit in order to ensure a linear relationship between
IR intensity and voltage. The reference voltage is 2.5V using a voltage divider, at zero current (zero
IR intensity). On a white surface, the output voltage is experimentally determined to be about 0.5 V.
The transresistive circuit output is fed into a non-inverting amplifier in order to increase the signal
strength.
